Being introverted means being drained by interacting with a number of other people, it's not specific to being indoors or outdoors. Getting away from people could just include going for a walk in the woods or sitting by a stream. The Japanese literally have a term for it, forest bathing. Getting out in nature is good for you.
If you'd meant indoorsy in the first place, you'd have used it to begin with. Chill out.
